Benard and thermal stress instabilities in a rarefied gas are investigated by the direct simulation Monte Carlo (DSMC) method. Particular emphasis is given to the numerical aspects of DSMC (accuracy, convergence, etc.), that were not investigated in the previous studies and to the refining of the simulation results by using a special data processing (filtering) procedure. In the stratified rarefied gases with hightemperature gradients the Boussinesq approximation is not valid and it is shown… CONTINUE READING
